Alleles and genotype frequencies and its distribution pattern for the highly polymorphic D1S80 locus were determined in a Korean population sample, especially in Kwangju and Chonnam, by using PCR followed by agarose gel electrophoresis with ethidium bromide staining, a procedure called the amplified-fragment-length polymorphism(Amp-FLP) technique. And the data were compared with the alleles and genotype frequencies of Finnish population, North American Caucasian, and Korean population(Seoul) which had been reported. In 203 unrelated Korean individuals 27 alleles and 84 genotypes were observed. The highest allele frequency was in allele M24(0.128) and tne next orders were inalleles M18(0.126), M29, M30, M31, and M28 and the other alleles showed relatively low frequencies. The highest frequency of genotype was in M18/M24 and the next order frequencies were M18/M30, M19/M27 M29/M29, and M18/M29. The homozyous genotypes were in 9 alleles such as M29, M24, M31, and M18, and most of heterozygous genotypes were composed of alleles of each homozygous genotypes and /or the other alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals were included. The VNTR D1S80 locus demonstrated a heterozygosity of 0.872. From the above results, VNTR D1S80 locus may be a powerful locus to identify individuals, however, the allele frequencies was not closely related to the genotype pattern, and the alleles of homozygous genotypes influenced on the chance of the recombination of the various genotypes. It is necessary to analyze the genotype distribution and the recombination pattern of alleles as well as alleles and genotype frequencies in each populations for statistical test at most highly polymorphic loci.

Colorectoanal intussusception is a rare and distinct entity that differs from the more common rectal prolapse. Typically the intussusception occurrs with tumor at the apex of the intussuscepted segment acting as lead point. Here we present a case and review the literature of colorectoanal intussusception. The case presented here is that of an elderly woman with a proximal sigmoid colon cancer at its apex. Anterior resection was electively performed after reduction of the intussusception. It is important to differentiate a colorectoanal intussusception from the more common rectal prolapse because treatment may differ. The anorectum remains in its normal anatomic position in colorectoanal intussusception, whereas the anal canal is effaced with the prolapsed segment of bowel in rectal prolapse. Identification of a tumor at the apex of the intussuscepted bowel should also arouse suspicion that the condition is not a rectal prolapse.

The authors analyzed clinical and radiographic results of the 87 cases which had done THRA with porous coated femoral stem followed up more than 2 years to study the difference of clinical and radiologic findings between the absence (group 1 ; 53 cases) and presence(group 2 ; 34 cases) of the porous coating in superolateral portion of the femoral stem. The following results were obtained : 1. Harris hip scores were improved 34.4 points from 56.5 points preoperatively to 90.9 points postoperatively in group Ι, and 32.7 points from 61 points preoperatively to 93.7 points postoperatively in group 2. The clinical results of the group 1 were Excellent in 45 cases, Good in 5 cases and Fair in 3 cases, and clinical result of the group 2 were Excellent in 33 cases and Good in 1 case. 2. The changes of femoral stem angle were below 2 degrees in 7 cases, above 2 degrees in 2 cases in group 1, and below 2 degrees in 5 cases, but not found more than 2 degrees of change of the femoral stem angle in group 2. 3. The osteolysis around femoral stem were 15 cases(28%) in Group 1, and 5 cases(15%) in Group 2. Diffuse osteolysis were 3 cases in Group 1, but was not observed in Group 2. 4. The vertical subsidence more than 2 mm was 3 cases in group 1, but was not observed in group 2. 5. The stable femoral stem were 51 cases in group 1, and 34 cases in group 2. The unstable femoral stem were 3 cases in group 1, but was not observed in group 2. Above results suggest that the porous coating in the superolateral portion of the femoral stem showed better results in radiologic and clinical findings in short term follow up.

Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. 82 cases of traumatic optic neuropathy were investigated to evaluate the effectiveness of high dose corticosteroid for the visual improvement. Age, sex, initial visual acuity, final visual acuity, interval to treatment, the type of trauma and the affected region were studied retrospectively.250 mg of Methylprednisolone was administered intravenously every 6 hours for 3 days, and then followed by tapering using oral prednisone The vision was improved in 36 of 82 cases[43.9%]. It was difficult to interpret the relation-ships between the affected region and visual improvement, the interval for each treatment and final visual acuity. However, the vision was improved in 45 of 50 cases who had an initial visual acuity of above light perception, but in the two of 32 cases with no light perception. If indicated, fifteen cases were treated with a combination of high dose corticosteroid and optic nerve decompression. In initial treatment of traumatic optic neuropathy, high dose corticosteroid was effecive. Whether or not initial visual acuity was better than light perception was a key risk factor in the outcome.

Many investigators were interested in the pathogenesis and the relationship between microscopical features and clinical behavior of hydatidiform mole. Trophoblastic cells in the trophoblastic disease were intensively examined histologically, ultrastructurally, immunohistochemically, and with hormone assay method, etc. But ultrastructural study on the stroma of hydatidiform mole was scarcely reported. In this paper, hydatidiform mole was examined at light and electron microscopic levels, with emphasis on the stroma. The results were as follows: 1) Hydropic degeneration of H-mole is more severe in the center of stroma and is not related with the degree of trophoblastic proliferation. Hofbauer cell and vascular structure are extremely rarely observed in the periphery of stroma which has relatively preserved cellular components. 2) Basement membrane is sometimes separated from trophoblastic layer. Degenerated cells in the stroma contain vacuoles, autophagosomes, and lipid droplets. Collagen is abundant in the loose interstitium. Hofbauer cells have no lysosome or phagosome. Vascular lumen is patient and endothelial cells are degenerated. From the above results, H-mole may be produced due to abnormal changes of trophoblasts and stromal changes may be a secondary process, so called autolysis. Hofbauer cells are not engaged in the stromal degeneration and may be different from usual tissue macrophages.
